Like listening to aseashell, the user can talk on the wrist communication device by cuppinghis/her hand over the ear and the device projects the caller's voiceinto the palm of the hand (FIG. 6).

The benefit of the wrist communication device 10 of the present patentapplication is to allow a user to conduct a private conversation withoutthe need to place any device onto or into his/her ear. This can beachieved by bone conduction, or by directly transmitting sound to theear. The following describes two different methods of utilizing boneconduction technology to transmit sound to the user's ear:

1. Bone Conduction Actuator on Wrist (FIG. 7)

The bone conduction actuator 24 may be provided on the communicationmodule 14 in contact with the user's wrist. When a finger of the user istouching the user's ear or other parts of the user's head, vibrationfrom the bone conduction actuator 24 can be transmitted through theuser's wrist, hand, finger and to the user's ear by bone conduction.

2. Bone Conduction Actuator on Finger (FIG. 8)

The bone conduction actuator 24 may be provided on the ring-shapedmember 30 to be worn on a finger of the user. When a finger of the useris touching the user's ear or other parts of the user's head, vibrationfrom the bone conduction actuator 24 can be transmitted through theuser's finger to the user's ear by bone conduction.

In another embodiment, the bone conduction actuator 24 and any othercommunication components provided on the ring-shaped member 30 may nothave to communicate with a wrist device. Instead, the bone conductionactuator 24 and any other communication components provided on thering-shaped member 30 can communicate directly with a smart phone or canhave its own SIM card.

FIG. 9 shows bone conduction speakers 24′ provided on the wristcommunication device 10 according to an embodiment of the present patentapplication. The communication module 14 may contain bone conductionspeakers 24′ which make contact with the user's skin. The boneconduction speakers 24′ can transmit sound via the bones of the user'swrist and finger so that when the finger is placed in/on the ear, or onthe user's head, the user can hear the audio.

In other embodiments, sound can be transmitted directly to the user'sear by other speaker support or communication component provided on thecommunication module 14. The speaker support or communication component,when not in use, may be retracted or concealed in the wristcommunication device 10. When the user needs to conduct a conversation,the speaker 22 on the speaker support can be extended into the palm ofthe hand of the user, as shown in FIG. 10. The communication module 14can transmit voice information via the speaker 22 into the user's palm.

The user can bring the speaker 22 close to the ear and cup his/her handover the ear, as shown in FIG. 11. The cupped hand acts as a part of thespeaker 22 by isolating ambient noise and directing the voice audio intothe user's ear. When the sound from the communication module 14 istransmitted into the palm of the hand of the user, the cupping gesturecreates sound isolation and allows the user to clearly hear the incomingvoice audio.
